...reasingly putting their trust in plastic fuel tanks. To serve the growing market in Asia and be closer to the customers, Basell, for example, has established a local production facility in Asia to make the global plastic fuel tank material, Lupolen 4261 AG. On the cost side, efforts are constantly being made to reduce the wall thickness of the fuel tanks to make them lighter. The foundations for an efficient tank are laid in the development phase. Here it is a question of using modern means of s...

The experiment was carried out on a blown film line using a (30´25D) laboratory extruder. The test material used was Lupolen 2420F from BASF, which was processed at 200°C. The film extruded in the first series of tests shows strong irregularities and local breaks spots in the circumferential thickness distribution (cf. red curve, Fig.7). Among the potential sources of erro...

Migration tests were conducted on eight different plastics (Ultramid B3, Polyclear T 86, Novolen 1100 T, Polystyrene 475 K, Lupolen 6031 M, Polystyrene 144 C, Luran 368 R, Terluran 877), each containing 1% chromium rutile yellow. The coloured plaques were immersed for 10 days at 40°C in different food simulants, usually 3% acetic acid, distilled water, 10% alcohol and test fat HB 307. In all the tes...

The product comparison is therefore based on a PE-LD (grade: Lupolen 2420 F, manufacturer: Basell), which is used for the production of, for example, plastic bags, carrier bags, diapers and laminating films. By contrast with most polyester grades, Ecoflex does not require predrying, since its hydrolysis stabili...

This is because biodiesel is less stable than conventional diesel fuel; it can change its structure at only 60°C and cause undesirable embrittlement of the plastic fuel tank in the long term. With Lupolen 4261 AG BD, LyondellBasell has launched an improved PEHD with long-term resistance to biodiesel. The experiences with light stabilizers were critical for this enhancement, since biodiesel causes chain rupture in a similar way to light exposur...
